Dualcaster Mage + Phantom Train + Vincent's Limit Break

Dualcaster Mage

Phantom Train

Vincent's Limit Break

How it works

1. Cast Vincent's Limit Break by paying its mana cost.
2. Holding priority, cast Dualcaster Mage by paying its mana cost.
3. When Dualcaster Mage enters, it triggers, copying Vincent's Limit Break, with the copy targeting Dualcaster Mage.
4. Resolve the copy of Vincent's Limit Break.
5. Holding priority, activate Phantom Train by sacrificing Dualcaster Mage.
6. When Dualcaster Mage dies, it triggers, returning it from your graveyard to the battlefield.
7. Repeat from step 3.
8. Resolve all Phantom Train abilities from step 5.

This clever loop hinges on Vincent's Limit Break to wrap a persistent resurrection effect around Dualcaster Mage, allowing it to continually target and copy the very spell that saves it. Whenever Dualcaster Mage enters the battlefield, its triggered ability intercepts the spell stack, while Phantom Train serves as the necessary sacrifice outlet to trigger the resurrection. Feeding Dualcaster Mage to Phantom Train not only sends the Mage back to the battlefield to repeat the copy cycle, but also pumps Phantom Train itself with endless +1/+1 counters.
